Introducing the Medieval Ass presents a lucid, accessible, and comprehensive picture of the enormous socioeconomic and cultural significance of the ass, or donkey, in the Middle Ages and beyond. In medieval times, the ass was a vital, utilitarian beast of burden, rather like ubiquitous white delivery vans today. At the same time, however, the ass had a rich, paradoxical reputation. Its hard work was praised but its obstinacy condemned. It exemplified the good Christian, humbly bearing Christ to Jerusalem, but also represented sloth, a mortal sin. It had a potent sexual reputationfdash;in one literary work, an ass had sex with a womanhdash;even as it was simultaneously linked to sterility. Over time, the ass also became synonymous with human idiocy, a comic figure representing foolish peasants, students too dull to learn, and their asinine teachers. This trope of foolishness was so prevalent that by the eighteenth century the word edquo;assrdquo; began to be replaced by tdquo;donkey. dquo; Introducing the Medieval Ass offers a wide-ranging account of the importance, and often surprising cultural prevalence, of this common domesticated animal.
